For any of you who have an older Powerbook G4 or an Ibook G4 take heed to my advice… be careful with your power adapter. I have been out of commission with my laptop for a few days because while I was working I began to smell what seemed like something burning only to figure out that my power adapter was smoking and almost caught on fire. Had I been sleeping or not at home at the time, things could haveĀ been exponentially worse. So I go online to apple to find in the reviews of this power adapter say similar things… so just be careful leaving your laptop plugged in for fear of it incinerating your prizeĀ possessions.
